Holley/Demon Carb stumble

I will keep that in the back of my mind. But the main reason, i'm jumping at the chance to remove them demon metering block. Is because i had to dig half broken off thread out of the back of the main jet holes due to a mismatch. Causing the back thread to have a u shape. Causing the end tread to be a straggler. had to bend and pull on the last threads to get them out of there.

I may go back to them block at a later date, and maybe should have done that. but if i can get it to run right with the 3310 blocks, and then think i what to experiment, i have a know good block to go back to if i get spun out in the weed.
